A geographic information system (GIS) is a computer based method integrating hardware, software, and digital data for capturing, storing, analyzing, managing and displaying geographically referenced information. The GIS Division of Bexar County Information Technology was created in November 2005 to develop a Bexar County GIS enterprise to promote expertise within offices and departments needing GIS; to coordinate with City of San Antonio and other governmental entities for the purposes of developing standards for security, accuracy, maintenance, format of GIS data for Bexar County; to develop a Bexar County GIS technical infrastructure; and to provide support, expertise and training to offices and departments in Bexar County using GIS.

The GIS group has developed multiple online applications which allow the constituents of Bexar County to view a variety of data about Bexar County and their own local area within Bexar County. Information regarding GIS projects can be found at
